Где ошибка: telegram client на хостинг?

Я зарегистрировал в "API telegram client" своего клиента, написал простенький код на python + Telethon.

from telethon.sync import TelegramClient
from telethon.sessions import StringSession
from settings import (API_ID, API_HASH, SESSION_STRING)

client = TelegramClient(StringSession(SESSION_STRING), API_ID, API_HASH)

client.start()

o_sebe=client.get_me().stringify()

f=open('mess_from_teleg.txt', 'a') # сначала откроем файл на запись
f.write(o_sebe)
f.flush()  
f.close() # закроем файл после записи

settings.py - в нём API_ID, API_HASH, SESSION_STRING

Проверил работу скрипта на компьютере: работает. Захотел выложить на хостинг PythonAnywhere и Heroku. Аккаунты бесплатные. Там и там скрипт не работает.

Вот логи после запуска скрипта:

PythonAnywhere
Запускаю скрипт и в консоли вижу следующее:

Heroku
После запуска в консоли вижу следующее:
